In the end everyone's biggest concern was around the expected temperature, as I have found out very quickly that Beijing weather can turn faster than Canberra's weather on an Urban Polaris (and haven't I experienced some beauties on that - heat wave in the morning and sleet in the afternoon). Given that the previous weekend had given us some significantly warmer temperatures only to be hit with a 10 degree drop in max temperature mid week, everyone was tempted to pack extra layers just in case. Being one of the Canberra folk who ride in the winter months I have a good selection of gear to pick from so I decided on the trusty GE longs and the arm warmers rather than going for something bulkier. It seems most other people had the same idea as well - positive sign number ONE.

Lucky for me I wasn't the only first timer on the ride. The other MOB virgins included an American who had been in Beijing for a few months and decided to take up his mate's offer to join in (and borrow his bike), an Italian guy who had been in Beijing for 4 years but had only just decided to get into cycling here, and a local girl we picked up along the way all of whom had varying levels of bike fitness. Being able to stick towards the front of the group at least showed me that while I didn't have the most endurance credits available for withdrawal from the quad bank, I certainly didn't have the least. Positive sign number TWO.
After what was a good 30-35min ride out to the NE of the city we jumped off the road verge and ducked under a bridge, finally getting onto a mixure of dirt and asphalt as we headed north-west along the Wenyuhe River towards the Olympic Green and beyond (depending on how keen we were later on). The road we were on was in a way arcing around the NE corner of the city - the question was, how far along would it go (and how far along it would WE go)?

This stretch along the river offered up a number of opportunities to ditch the tar in lieu of dirt trails to either side of the road, but we stuck with the sealed option most of the way until the Italian recruit Miso took a last minute detour towards the river and lead the whole group into some spontaneous singletrack action. Just some simple walking track that ducked around and over little mounds of dirt just off to the side, with a pothole every now and then to keep you on your toes. It was no Sparrow or Stromlo (or even up there with some of Canberra's best urban skinny) but in a city of 19 million people beggars can't be choosers. In the end though it's the people's reactions that are the best judge and the smiles on the faces of the group as we pulled back onto the road told the story.
With the legs finally experiencing some (any) variations in gradient we all woke up our lungs and took the opportunity to pull up stumps for a bit of a rest and a photo opportunity. The good thing about China is that most people in the streets are willing to take a photo for you, and don't seem to be put out at all. Any residual risk of us getting an unhappy camper to ask was soon put aside when a local pulled up next to us on a Merida racing bike - a bit unexpected in an area of Beijing where many of the back roads were still a bit rough. And this guy's bike was certainly not kitted for carrying home the groceries in a front basket - it was made for speed.
The starting group at the 1st rest stop (location A on the map below)
From L to R: Il (Russia), Andrew (Russia), Me (Aussie), Xingou (China), Miso (Italy), Vicky (China), Jonathan (USA), George (UK), Landon (USA)
By this time one of the riders was starting to feel it more than the others, and was looking to head back as soon as we got off the trail and headed back towards the centre. Luckily for her (and for me as well) the next part of the ride up to the 2nd rest stop consisted primarily of a sealed road along the edge of the canal, with nothing in the way of undullations except for one little rise.
When the group came to a bridge blocking the way we took it as an opportunity to let the group reform and grab a drink/snack and also for George to consult his GPS for a location check. Once he confirmed that we were in the right vicinity we detoured around the bridge before ducking back onto the path for another kilometer or so before we hit the trainlines marking the near end of our canal traverse. Up and over with the bikes over the shoulder and we were doing the last few hundred meters through some of the heavy migrant worker resident areas before turning left onto a major road and heading south back towards the city via the Olympic Green. This last stretch before the major road certainly had some fun bits in it, including a rather sharp descent down from the train tracks and some seriously eroded (albeit short) rocky shutes. Letting go of the brakes too keenly here and it might have ended up as a swim in the abnornally viscous canal (did I mention ambulance?).

BUSTED. Nature calls, and not a tree in sight.

Not the best part of MTB riding, and in the end I could have actually just ridden a bit futher along and connected to a trail up. DOH!
Shortly after we hit the run down to the Olympic Park we had a few of our riders peel off to head straight back home (mix of family and fatigue), while the rest of us headed down alongside the Bird's Nest Stadium for a bit of sightseeing. After the obligatory 2nd photo we agreed that food and beer/wine was the next order of business and I left it to those more experienced in the NE Beijing dining scene to select a place for lunch (although I gotta say the final choice was a winner in my books).

"No parking of...eerrrr....never mind".
All up it was a great ride especially for someone new to the city, with the finishing group having clocked around 60km. Having an OK sense of direction I'm confident I could do it again on my own and it would make a good training loop. For the moment though I have decided to try out a few trails closer to home, and along with the Italian guy on the ride get our fitness up a bit before we hit the hills to the west of the city with the group. This weekend the group is looking to explore the same canal/river but in the area to the NW of the city, up towards the Summer Palace (one of the must-visit places in Beijing). Unfortunately I'll be missing this one as we are heading down for some Shaolin Monk action for the weekend but hope to be able to report on their ride planned for 3 weeks time (wherever that might be).
Below is a very rough mark-up of the route we took (although the return south to the city may not be exactly right).
